The perfect solution for RF communication lab courses
GSP-730 is a 3 GHz spectrum analyzer developed for RF communication teaching needs. Budget constraints and lack of teaching tools are usually the two major obstacles for schools to provide high-quality RF communication lab courses, the GSP-730 is a mid-level spectrum analyzer that provides all the basic functional features expected of a spectrum analyzer, and paired with the GRF-1300A training kit, it is uniquely positioned in the field of 3 GHz RF communication lab courses with its compromise price.
The GSP-730 Spectrum Analyzer, GRF-1300A, and USG Series RF Signal Generator are properly connected to the computer to form a triangular-structured system integration that allows for continuous experimentation while lecturing. The teacher can use the computer to show the presentation of the teaching content, while controlling the GSP-730 with the GRF-1300A and USG series to conduct experiments, reading the spectrum display and parameters and displaying them on the computer screen. The GSP-730 and GRF-1300A are easy to switch between current teaching materials, including presentations, textbooks, remote control software, in an electronic lab system.
The GSP-730 and GRF-1300A RF communication systems are suitable for universities, colleges and universities, vocational schools and training centers, and individual basic learning in electronics and communications. Replacing the new training system saves huge cost of use, combining the GSP-730 and GRF-1300A provides an economical solution to eliminate the two major obstacles of budget constraints and insufficient teaching tools.
